还可以使用正则表达式来表示参数,这样可以通过正则表达式来设置匹配规则,例如。 //Match only inbox ids that contain//6 hexidecimal digitsurl: '/inbox/{inboxId:[0-9a-fA-F]{6}}',//Or//match every url at the end of `/inbox`//to `inboxId` (a catch-all)url: '/inbox/{inboxId:.*}' 注...

ComponentRef.setInput will only set the input on the component if it is different from the previous value (based on Object.is equality). If code relies on the input always being set, it should be updated to copy objects or wrap primitives in order to ensure the input value differs from ...

You can also enable eager card type detection to match against card type with only leading digits (e.g. a4can immediately be detected as a Visa). Add thecc-eager-typeattribute to your element to enable eager type detection. The eagerly matched type will be available as$ccEagerTypeon the ...
